I am afraid the general public does not share your fetish about phone sizes, Harry. Most folks think a wide variety is pretty cool.

The crucial difference between your examples and something like the Galaxy Note is the width of the device and that is the true limiting factor on how large a device is comfortable for people to use and unless somebody has particularly large hands then current devices like the gsiii or the note are about the limit as far as how big they can go before they would be too uncomfortable to hold as normal phone.
